Abstract (en)
The invention provides a monitoring process of a manufacturing system, such as assembly line in the automotive or aircraft domain. The system comprises a plurality of manufacturing stations which are configured for manufacturing a workpiece. The monitoring process comprises the steps of: obtaining (100) video stream data of a moving arm transporting successive workpieces from the first manufacturing station to the second manufacturing station of the manufacturing system; the moving arm exhibiting a first end receiving the workpieces successively; inputting (106) the video stream data in a convolutional neural network algorithm in order to generate an arm digital representation of the moving arm motions; computing (108) operation data, such as time series data, of the manufacturing system by means of the arm digital representation; inputting (110) the time series data in a machine learning model in order to compute manufacturing data; generating (112) a signal if the manufacturing data meet a predefined condition.
